Between Tiny Furniture and Girls, Lena Dunham has made her name chronicling the very specific experiences of 20somethings in modern-day New York. But now she’s taking those skills to an entirely different era.

Dunahm is set to write and possibly direct Catherine, Called Birdy, an adaptation of the award-winning YA novel by Karen Cushman. The story follows a 14-year-old girl in Medieval England avoiding marriage to an unattractive suitor. Hit the jump for more details on the Lena Dunham Catherine Called Birdy movie.
